yes 3mm head hasket with arp studs, 93 octane pump gas

 

Full-Race kit.

 

Nice work Jeff!

 

tuned @ UMS Tuning


the clutch (exedy twin) started slipping @ higher boost levels


pump gas was 16 psi and race was set @ 23 psi

Re-tune after clutch and fmic are replaced

 

i just got a full-race manifold, and kept everything the same from my old ultimate racing kit.

This is full-race manifold, 3inch DP, 3inch single, and 750cc RC injectors and a 60-1 Hi-Fi

Low Boost 11psi 425whp 290ft/lbs, high boost 18psi dropping to 16 psi at redline 475whp 365ft/lbs (DynaPack). On a mustang dyno with high humidity and 90+ weather it was 460whp and 340ft/lbs on high boost!

 

so the full-race manifold bolted up to UR racing dp no problem?

 

i had made my own DP, but it fit. I did have to move the vband flange around on the TP so it would line up perfectly. I made 415-420whp at 18psi with the old manifold, i now make 425whp at 11psi! Crazy what a well designed manifold can do for your power!

 

Its strange that kutsujula made less TQ then passmans2kny... and they have the same kit.. is it because one was useing a smaller turbo?

 

the compression is different and again not to take away from passman but different dyno's.

 

i was tuned at jeff evans (where Passman was tuned) and made 475whp and 365ft/lbs of torque. One week later i went to a Mustang Dyno and made 460whp and 340ft/lbs of torque, so the difference between the two isn't THAT drastic.
